For this case we must simplify the following expression:

$\frac {2} {5} - (- \frac {3} {4})$

By definition of the law of multiplication signs we have to:

- * - = +

So, rewriting the expression we have:

$\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15$

Thus, the answer in decimal form is 1.15.

$\frac {23} {20} = 1.15$
